There is nothing physical to find at the posted coordinates, but they are the start of the Adventure Cache John Venezia Community Park. You will need to compete this lab cache in order to find the coordinates for this bonus. Link for the Adventure Lab is https://adventurelab.page.link/Ub9g
Coordinates are: N38 AB.CDE W104 FG.HIJ
I added the bonus long after the Adventure cache was initially published...If you have already completed the lab, you will need to go back in to the lab, open up the locations and then open logbook (confirmed that updated logbook will show you the clues).
